How to find the list of users who have "approved" the changes in these pull requests.

Answer 1

You can do this by using the List Reviews for a Pull Request API endpoint. For the example PR you've listed this would be:

GET /repos/harsh-groverfk/jenkins-demo/pulls/16/reviews

This will output all reviews done on a PR (example from the docs):
